BD-SPRING.

SPEQIFICATION forming part of Letters Patent No. 257,851, dated May 16,1882,

' Application filed February 25, 1882. (No `model.)

u Links; and I do hereby declare the following to be a full, clear, andexact description ot' the invention, such as will enable others` skillediii the art to which it appertains to make and use the same, referencebeing had to the accoinpanying drawings, and to letters or figures ofreference niai'ked thereon, which form a part of this specification.

My invention relates 'to a spring and link for bed-bottoms, shown anddescribed in an application pending hei'ewith, though not claiinedtherein; and it consists in a peculiar-shaped link, iii combination witha pecular-shaped connection iii twin Springs, and iii said link as Iconstituting a member of the component parts of coiled-springbed-bottoms, as hereinafter fully described, and speciticall y setfoi'th in the claiins. i

Figure l is a plan of a set of Springs peculiarly adapted to my liiik,as shown there-in emploved; aiid Fig. 2 is a detached view of said link,and Fig. 3 a detail, showing the clamp at the lower end of the springs.

The object of my invention is to construct, arrange, and connect spiralor coil Springs iii such a manner that the entire surface ot' thebed-bottom forined thereof shall be such as will support the mattress atall points and at the same time shall yield to pressure applied in alldirections thereon-that is, Vertically, laterally, longitudiua-lly, ordiagonally, in a downward direction-and at the same tiine have agenerally plcasing appearance in outine. each spring is constructed withsuch a connecting poi'tion to its in ate that in form it is adapted toharmonize with the form of the link employed to connect said springswith others than its mate, and at the saine time have or possess in thatform of connecting portion elasticity in like directions relative to itsoutliiie as does said connecting-link. I apply the name connectingportion'7 to that whichunites two Springs and is integral therewith, andthe name connecting-link to that which nnites twospringsandisnotintegral,butattachedthereto.

To accomplish this object mechanically.

My link A, as shown clearly in Fig. 2, is S-shaped, with loops c c, andalso the connecting portion of the springs should be S--shaped, eithersingle, double, as shown, or any number of S-shaped convolutions. Itwill be observed that the links A connectiiig spriiigs not niates arelongitudinally and transversely disposed iii the bottom in uniform.relative position, as shown at a a a a, while when connecting links andnot springs, as at b, they are turned at right angles to the positionjust referifed to, so that they are adapted to be attached to theprominent curves of either the springs or theinselvcs, and are asarranged elastic in the same direction as the part to which they :arecon-` iiected, whereby a pleasing appearanc'e iii outliiie is secured tothe whole bed-bottoin, iu addition to the mechanical adaptability of theindividual elements of the bottom to each other, and a yielding elasticsupport in all direotions and uniform in area-that is, having nounsupported or rigid points thereiu. The bottom coil of each spring isadapted to be attached or fastened to the slats by means of a clainp, B,foriiied integral with the spring by beiiding the wire contiguoiis tothe lower coil thereot' downward at d and then iiiward at e, andreturning, as atf and g, leaving the end g abutting against the undersurface of the coil, as

`shown in Fig. 3.

Having described iny invention and its operation, what I claim as new,and. desire to secure by Letters Patent, is-

- 1. In a bed-bottom, the combination of twin spriiigs having S-shapedconnecting portions, withayieldingconnecting-link of substantially SShape, substantially as shown and described.

i 2. As an article of manufacture, the vielding connecting-link A, beingsubstantially S shape, and adapted to be attached to the coils of aspring, substantially as shown and descrihed.

3. In a bed-spring, the ('lainp B, consisting of the parts d eg, formedintegral with the spring, and having the end g abutting againstv theunder surface of the final coil thei'eof, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.
